To all whom t 'may concern:

Be it known that I, CiiAiiLics 1V. Bowan', a citizen of the United States, residing at Lynn, in the county of Essex and State ef Massachusetts, have invented certain new and useful Improvements in Methods of Making Heels; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaiiis to make and use the saine. f

v This invention relates to a method of inakingheels and more particularly to a method by which heels may continuously.

Heretofore three general methods have been devised and used for making heels from Whole lifts. By the first method, most generally7 in use, \the heels are built singly by hand in a form which alines the component lifts, using the same form repeatedly after each ejection of a completed heel. An eX- ainple of the type of machine employed in practising this method is shown in the patent to Eliphalet A. Tripp No. 1,056,720, granted March 18, 1913, on an application filed June 9, 1909. By the. second method, little practised at present, a mechanical collecting device for the component lifts is substituted for the hand operation of the lirst method and this device delivers the collected lifts to an alining device, the entire operation being repeated for each heel that is built. An example of the type of machine for practising this method is shown in the present applicaut"s prior Patent No. 1,146,996, granted July Q0, 191.5, on an application tiled August 16. 1907. 1t vvill be recognized by those skilled in the art that the tivo methods just described a're defective iiiv that the require ment for completing one heel before another can be commenced reduces the output of the operative and renders the entire operation slow and undesirable. Accordingly by the third method it has been proposed to employ an' apparatus which will enable the operative to build a plurality of heelsat the same time, the mode of operation being such that completed heels are being delivered continuously While other heels are still in process.

By using'this method the delay heretofore be made in multiple Serial No. 245,481.

yield. An example of the type of machine employed in practising this method is shovvii livery of completed heels is limited to one y heel for each third handling or deposit of a series of lifts at the building station. It will be obvious to those skilled in the art that the most rapid method of building heels in multiple would be that in which a completed heel is delivered at each successive handling or deposit of a sei-ies of lifts at the building station. By perfecting the multiple method in the manner just described the delivery of heels in the saine period of time is increased threefold over the delivery from the Winkley apparatus.

The object of the present invention is to improve upon present known methods of -making heels in multiple by introducing positing a series of lifts at a time, and will.

permit each such series to be advanced simultaneously beyond the stations of deposit and intermittently through succeeding stations. As illustrative of one form of apparatus that may be employed a diagrammatic representation is given of the essential features of a heel building machine illustrated and described in the inventors (to-pending application filed December 9, 1912, Serial No. 7 35,750, from which this present application is a division.

The improved method Will be explained with the assistance of the accompanying drawings in which:

Figure 1 is an elevational vievv of the lift collecting apparatud employed in one forni of the machine of said parent application, at the building station to Which vthe successive series of lifts are delivered,

Figs. l and 2.

In practising the novel method the heellifts are obtained from a series 0f sources of supply which are arranged in a row to facilitate handlin the lifts in series. Where vheels of the uban, military or like type.

having a slanted or .pitched back, are to be produced, a lift of a diderent size will be obtained from each source of supply.' To simplyfy an explanation of the method it will be assumed that a tive-lift heel, having a itched back, is to be produced, the largest li t being vobtained. from the source of supply at the right-hand end of the series and the smallest lift from the left-hand end.

Since heels are to be built in multiple lifts must be obtained from the sources of supply and transferred to the building station in successive series, and in the present 'method .the lifts deposited at the building station at each lift handling operation are equal in 'number to the number of lifts in the heel to be built.y Any convenient device for handling lifts in series may be used` for example pickers of the type illustrated in Figs. 68 and 69 of the patent/to Emmet Horton No. 760,791, granted May Q4, 190i, or, if the lifts are to be obtained from strips of sheet material, dies such as illustrated in' said parent application, may be used.

lVhen employing the form of apparatus disclosed more particularly in Fig. l() of said parent application each series of lifts is deposited .at a building stationhaving the form of a--iiat bed 2 provided with a slot el extending from end to end thereof. The lifts of each Aseries are deposited at different stations on the bed, over its slot, and the corresponding lifts of each successive series are deposited at the same station. ln order that the successive deposits of lifts may superpose the lifts on each other so as to vbuild heels in multiple suitable mechanism may be employed for intermittently advancing all the lifts simultaneously,A from the stations of deposit to the next adjacent stations in the row, during the intervals between the successive deposits of lifts.

One form of feed mechanism, which acts directly on the heel-piles formed by the deposited lifts, is illustrated in said parent application. In using this mechanism a series of feed fingers 6, equal in number to the number of lifts in the heel, are intermit tently projected upwardly through the slot 4 in the rear ofv (at the breast end) each of the deposited lifts, then are moved in the line of the row a suiiic'ient distance to ad- Vance the lifts to the next adjacent stations in the row, and then are Withdrawn and asseiiibling bed which :Lesen-ea returned to their original positions. 'llo impart vthis four-motion feed movement to the fingerst, they are secured to a carriage 8 which is adapted to reciprocate bach and forth a distance equal to the space betiveen adjacent stations. The carriage 8 is recip rocated by 'a cam ltl'and lever l2 carrying a gear segment le which meshes with a rack on a sub-carriage i6. Rolls i8 on the car riage 8 co-act With cam-surfaces 9.0 Aon the sub-carriage which "terminate in shoulders The-'sub-carriage is supported .on a slide Q4, sustained on a sub-bed 26. by rolls 28 contained between pairs of stops 30 and 32 on the slidef A friction device engaging the slide and snb-bcd restrains the movement of the slide..v Upright guides 36 on the slide are engaged by projections on ythe carriage 8 and prevent horizontal movement of the latter relative to the slide. rllhe inode of operation will be obvious from the foregoing description. .Si movement of the gear segment to the left in Fig. l will iirst by moving` the subrarriage relatively 'to the carriage 8, raise the fingers't, then the tvvo carriages move together thus advancing the lifts which are in front of 'the fingers. On the return swing of the gear segment lingers are first dropped belowv the bed 2 and then returned to their first position. Side guides 38 ma;Y be provided for alining the superposed lifts properly.

ln this Way the lifts are advanced step- .by-step through each of the stations beyond the station of deposit and after each step the pile is increased by one lift, so that finalljv after passing the last station in the row the heel piles are complete. graphic representation of the man .er in which the heel piles collect additional lift` at each successive lift handling operation is given in Fig. 3 of the drawings.

lt is preferred to secure together the .lifts comprising;` each heel.. An adhesive is the most suitable medium for this purpose a in the apparatus disci .a in said pA aj'iplica'tion a bar i0 is vided above the stains a series of paste brushes These brushes depend into positions between the stations at which lifts are deposited so that each series of deposited lifts is advanced they are swept beneath the brushes and receive a coating of paste ou their upper exposed faces. The brushes may be rcj lenished With p te from time to time by the means described in said parent application.

When the heel piles are completed they are delivered successively at one end of the rovv of stations at each forward step, and thereafter the lifts of delivered heel may be additionally secured by driving a nail through them. it may be here stated th at some shoe manufacturers secure the lifts by nails alone but obviously it is within the Sil ' it will be observed thus` provide p a heel nailing mechanism 'and each, after having received a nail therethrough, is ejected by' the other advancing heels.

Referring again to the diagram of Fig. 3 that if the sequence of steps there set forth is followed, starting with a single deposit of lifts at line` a, incomplete heels will be delivered at the 2nd, 3rd and 4th handling of the lifts, namely at the left on lines 6,0, and d. This waste may be avoided by completing the partially built heels by a hand operation.' In practice, however, this is taken care of lby the operative who, before beginning to deposit the lifts inl series, will place one, two, three and four lifts on the 2nd, 3rd, 4th and 5th stations respectively as 'shown on line d and for the delivery of a complete heel at each subsequent deposit of a series of lifts. By takingthis precaution,- the" stations are always loaded with lifts as on lines e and f after each lift handling operaf tion.

Obviously a heel of any desired size may be built in multiple simply by varying the number of lifts composing each deposit. -In this connection particular attention iscalled to the fact that in this application the term lift is used in an inclusive sense as defining any blank capable of being utilized in buildin-g heels, irrespective oflthe particular shape which the blanks may have when they are 4first collected in the form of pile.

Those skilled in the art will recognize that the apparatus illustrated is not the only apparatus which may be employed'I to assist in building heels in multiple when utilizing the principles enunciated in the foregoing de scription, the appended claims which define the true scope of the invention.

Having thus described thel novel process to employ enlyA and reference should be made toof rest; and applying .pasteto each series;

.whereby as the lifts are advanced additional lifts are simultaneously,collected and a 'heel :is delivered at one end of the row of stations at each forward step.

2. The method of building heels vin multiple which includes the steps of depositing in a row a seriesl of lifts, equal in number to the number of lifts in the heel lto be built,

each lift at a different station; intermittently advancing saidlifts simultaneously through succeeding stations in the row; depositing an additional series of lifts, equal in number to the first series, at each period of rest; whereby as the lifts are advanced additional lifts are simultaneously collected and a heel is delivered at one end of the row of stations at each forward step; and securing together the lifts of each delivered heel.

3. The method of building heels in mul- -tiple which includesthe steps of repeatedly depositing successive seriesof lifts at a series of stations in a row, the corresponding lifts `of each series being deposited each at the same station, and the number of lifts in each series being equal to the number of lifts in the heel to be built; intermittently advancing all the deposited lifts slmultaneously, from the stations of deposit to the next adjacent stations in `the row, during the intervals between the successive deposits of lifts; whereby the heel piles increase in height at each advanceand a heel of the desired height is delivered when the number of stations through which the lifts have been advanced is equal to the vnumber of lifts required in the heel; and securing together the lifts comprising each CHARLES W.
